Born to parents George and Adeline Carstairs on 25 March 1900, George "Bluey" Carstairs went on to become a legendary figure at the St George Dragons club. He learned the game of rugby league at Kogarah Marist Brothers, where he attended as a student. He made his first grade début in St George's foundation year in 1921, and went on to play his whole career at the club between 1921 and 1929. He had the honour of scoring the first try in St. George's first competition match on 3 April 1921, in a game that saw Glebe defeat St. George 4–3. At years end, he was selected to play on the 1921–22 Kangaroo tour of Great Britain, thus making Carstairs St. George's first international player. He is listed on the Australian Players Register as Kangaroo No. 123.[1] He played in the 2nd and 3rd test matches on that tour. This happened to be his last representative appearance, either for Australia or his state. A loyal clubman, George Carstairs was involved in the massive controversy surrounding the Earl Park Riot, a 1928 match involving St George and Balmain Tigers that turned into an all in brawl with players and spectators alike.[2] Carstairs retired at the end of the 1929 season.

George Carstairs bravely served in the both world wars. He enlisted in the AIF in January 1917, claiming he was 18 years of age, whilst being only 16. He sailed out with the 1st Battalion/24 Reinforcements on 17 February 1917 to see action in France, and returned to Australia in 1919 at war's end.

He also enlisted in the Australian Army during World War II in 1940, aged 40, and saw action in the Middle East before a war related injury forced his discharge in 1943.

Brave until the end, George Carstairs died from complications due to old war injuries at the Concord Repatriation Hospital on 14 October 1966, aged 66.[3]
